Help please. Need a simple explanation. ​
lbvjy [14]

Answer:

B) 20

Step-by-step explanation:

Each number in the equation needs to be a whole number, since you can't have 2.5 marbles or something like that.

2/5 of 16 is 6.4

2/5 of 20 is 8

2/5 of 21 is 8.4

2/5 of 26 is 10.4

Even though 20 is the only one that works, if you wanted to be sure it's right, just divide by three after subtracting 8 (the three remaining marbles.)

20-8=12

12÷3=4

The three remaining numbers would be equal and the amount of yellow numbers is a whole number. 20 is correct

Which equation is equivalent to 2 4x = 8x-3
Stolb23 [73]

Answer:

x = -9

Step-by-step explanation:

the equation is 2^4x = 8^x - 3.

therefore 2^4x = 2^3(x-3)

since both have powers of 2

therefore

4x = 3(x-3)

4x = 3x - 9

4x -3x = -9

x = -9
